But hmm, tangentially related, but Yan do we have a similar problem with
KVM_PRE_FAULT_MEMORY after we started setting pre_fault_allowed during TD
finalization?

Sean's commit 6385d01eec16 ("KVM: x86/mmu: Don't overwrite shadow-present MMU
SPTEs when prefaulting") should have prevented repeated invocation of
set_external_spte_present() with prefaulted entries.

Ok, great.
